` DISPENSING DEVICE` I Filed June 16, 1933 /N Lag/I@ Patented Dec. 18, 1934 UNITED STATES maitre PATENT OFFICE 1 Claim.

My invention consists of a combination tothbrush and tooth cleaning paste or powder reservoir, compactly built so that one may conveniently carry this dentalette set.

A principal object of this invention is to supply a dental set for travelers, school children and all people seeking dental hygiene.

Another object is the construction of this invention in such a manner that the paramount qualities are its simplicity; ease of operation; few operating parts; replacement of new brushes and applicability to any type of cleaning compound used. A

Another principal object is to provide a sanitary reservoir for the cleaning compound and also for the toothbrush. This object and other results are obtained by means of the invention as outlined in the following description and numerals which refer to similar numbers as shown on the drawing accompanying this application.

Fig. 1 is a longitudinal sectional View of the invention showing how the container for the cleaning compound and also the container for the toothbrush are compactly built and the position of the toothbrush and the parts essential to operate the method of feeding the compound are also shown.

Fig. 2 is a cross-sectional view on line 2-2 of Fig. 1 of brush container showing position of toothbrush and handle and method of attaching handle to brush.

Fig. 3 is a cross-section on line 3-3 of Fig. l showing closing valve of the container.

Like reference characters refer to similar parts throughout the diierent views of the drawing and in which 5 designates a container built in a cylindrical shape which serves as a depository for the toothbrush 20 and 21, handle 24 and also a small sanitary pad 30 at the closed end and into this pad one may place a few drops of any type of antiseptic for sanitation of the brush. The open end of the container 5 has small threads 29 which screw over the container 6 by means of the threads 15. This container 5 also has a small groove 8 around the outside near the closed end into which fits the safety clasp 7, if desired. 25 designates small holes to permit ventilation of the brush.

6 designates a container or reservoir for the cleaning compound and is built in a cylindrical shape, in which the type of paste or powder used may be kept until desired. 'Ihis container 6 is screwed into 5 by means of the threads 15 into threads 29. 9 designates a rod that extends longitudinally inside of container 6. At the closed end of container 6 rod 9 is attached to a narrow disk shape plunger 10 by means of a small threaded hole 12 in plunger l0 and held secure by a small nut 11. This plunger 10 moves in a longitudinal manner inside reservoir 6. Rod 9 also nts through a hole 16 in a head 13 and has enlarged cap 19 which is gripped and pulled outward causing plunger 10 to move in a longitudinal manner compelling expulsion of cleaning compound through opening 17 in the head.

Head 13 is a narrow disk that fits tightly into container 6 at the open end, by means of threads 14 into threads 31, which are on the inside of container 6, and has hole 16 through which rod 9 slides. This disk also has the opening 17 at the bottom permitting the passage of the paste or powder when forced outward by the sliding of plunger 10. 18 designates a small semi-circular valve that is attached to disk 13 by means of a` small screw 26 extending through valve 18. The object of disk 13 is to prevent seepage of paste or powder or the entering of any foreign substance. 20 is a small brush on base 21. This base has a small groove 22 on each side into which nts 23 a grip for holding the toothbrush 20 and base 21 which also forms part of the handle 24. This handle 24 has two extensions 28 which permit expansion or contraction of the handle. This result is obtained by the handle being built with the one end large and round and tapering gradually. When expansion is desired one may merely pull on end of handle and the narrow openings slide forward toward large end wedging handle firmly.

The operation of this invention is very simple.` One merely unscrews cap or container 5; drops out toothbrush 21; extends handle by pulling end handle 28 to desired length. Valve 18 is turned, opening passage 17 and rod 9 is pulled outward by gripping knurled end 19 which pulls plunger 10 outwardly, forcing cleaning compound through passage 17, onto brush which is held adjacent thereto. 27 designates a Vent hole in end of container 6.

When the reservoir 6 is empty it may be filled by unscrewing the knurled end 19 and parts 18 and 13, leaving rod 9 in place. The tube of paste or can of powder is then pressed or poured into the reservoir 6 until lled, then removed parts and knurled end are replaced.

While I have illustrated and outlined the preferred invention, the invention is subject to modiiication in many details of construction and arrangement. I therefore do not wish to be restricted to the specific details shown and described 10 rod extending through theclosure and having a piston on its inner end; said rod having a nger knob on its outer end and said closure having a discharge port whereby, .when the rod is pulled by effort on the knob, contents of the magazine may be expressed through the said port; the knob being removable from the rod and the closure being removable from the magazine to permit filling of the latter while the piston is in remote position in the magazine.
